tests: make tests to run parallel

Unarguably this change makes test output to be more messy, but when I
compare run time tells with clear numbers parallel is quicker.  For me
the quickness is important factor.  Running test suite always after a
change is preferrably quick, and if something is indicated to be broken
it is ok to spend time in drilling down what happen.

$ time ./tests/run.sh --parallel=5
[...]
real    1m48.037s

Same without parallelization.

$ time ./tests/run.sh
real    3m16.687s

The default is changed to be parallel, where job count is same as number
of CPUs.

[kzak@redhat.com: - propagate --parallel into function.sh
                  - don't use extra title for non-parallel execution
                  - disable by default]
